Two of the most talked-about cordless handheld vacuums on Amazon go head to head today: the BLACK+DECKER Dustbuster AdvancedClean (CHV1410L), the long-running classic that sits at the top of Amazon's handheld vacuum charts, and the Shark UltraCyclone Pet Pro Plus (CH951), the pet-hair specialist with a motorized power brush. If you are a first-time car owner trying to decide which one belongs in your trunk, this comparison lays out the real differences — suction, pet hair, runtime, bin size, and value — so you can pick with confidence.

The contenders
Shark UltraCyclone Pet Pro Plus CH951
- Motorized self-cleaning pet power brush that resists hair wrap
- 80W motor with dual cyclonic air streams for strong, consistent suction
- CleanTouch dirt ejector — empty the bin without touching debris
- Crevice tool + scrubbing brush included; washable filter
Pros: Excellent on pet hair and embedded dirt; motorized brush genuinely makes a difference on upholstery; independent lab testing measured ~14.7 minutes of real runtime; compact and easy to maneuver.
Cons: Smallest dust bin here (0.43 L) — pet owners empty it often; 4–6 hour charge time is slow; slightly heavier at 2.8 lb.
Best for: Drivers who carry dogs or cats — the pet power brush is the whole point.
BLACK+DECKER Dustbuster AdvancedClean CHV1410L
- #1 best-selling handheld vacuum on Amazon — a proven, decade-long classic
- Generous 20.6 oz translucent bowl means fewer trips to the trash
- Rotating slim nozzle reaches under seats and into tight gaps
- Flip-up brush + crevice tool onboard; washable filter; charging base included
Pros: Huge review base and long track record; biggest dust bowl in this comparison; rotating nozzle is genuinely handy between car seats; typically the cheaper pick; simple to empty and maintain.
Cons: No motorized brush, so embedded pet hair is harder work; ~10–12 minutes of runtime per charge; the wide body can feel bulky in the tightest crevices.
Best for: General car cleanup — crumbs, dust, sand, and everyday messes on a budget.
Head-to-head: the details that matter
Suction and cleaning power
On paper the Shark has the edge: its 80W motor with dual cyclonic streams delivers strong, steady suction that independent reviewers consistently rank above the Dustbuster's 16V system. In practice, both handle loose crumbs, dust, and sand on car seats and floor mats without drama. The difference shows up on stuck dirt — ground-in debris on carpeted mats and upholstery — where the Shark pulls ahead.
Pet hair — the deciding factor for many
This is the Shark's home turf. Its detachable motorized pet power brush agitates fabric and lifts embedded hair, and the self-cleaning design resists hair wrap. The Dustbuster has no powered brush — its flip-up brush helps on surfaces, but woven-in dog or cat hair takes multiple passes and more effort. If a pet rides in your car regularly, this single difference settles the comparison. For a deeper look at pet-specific cleaning setups, see our best car cleaning kits for pet owners.
Runtime and charging
Neither is a marathon runner — both give you roughly 10–15 minutes per charge, enough for a full interior touch-up but not a neglected minivan. Independent measurements put the Shark at about 14.7 minutes and the Dustbuster at about 12.4 minutes, so they are effectively tied. The Dustbuster charges in about 4 hours on its included base; the Shark needs 4–6 hours. Tip: keep whichever you buy docked and charging between uses so it is always ready.
Dust bin and emptying
The Dustbuster wins on capacity — its 20.6 oz (0.6 L) translucent bowl holds noticeably more than the Shark's 0.43 L bin, so you empty it less often. The Shark answers with the CleanTouch dirt ejector: one press dumps debris hands-free, which pet owners will appreciate. Both filters are washable; rinse and fully air-dry before reinstalling to keep suction strong.
Weight and handling in a car
At 2.6 lb vs 2.8 lb, both are light enough for one-handed use overhead and under seats. The Shark's slimmer profile slips into seat crevices a little more easily, while the Dustbuster's rotating nozzle compensates with reach. Both are far more practical in a parked car than a corded alternative — see cordless vs corded car vacuums for why that matters.
Attachments
Dustbuster: rotating slim nozzle, pull-out crevice tool, flip-up brush. Shark: motorized pet power brush, crevice tool, scrubbing brush. The Shark's motorized brush is the most valuable single attachment in this comparison; the Dustbuster's rotating nozzle is the most clever non-powered one.
Value for money
The Dustbuster is typically the cheaper of the two and carries a 100,000+ review history at 4.4 stars — remarkable staying power. The Shark usually costs more, and you are paying for the motorized pet brush and stronger suction. Both carry 2-year warranties.
Which one should you buy?
Run through this quick checklist:
- You transport a dog or cat → Shark UltraCyclone. The pet power brush is not marketing fluff; it is the tool that makes embedded hair manageable.
- You want the cheapest reliable option for crumbs, dust, and sand → BLACK+DECKER Dustbuster. A proven classic at a friendly price.
- You hate emptying the bin mid-clean → Dustbuster, with its much larger 0.6 L bowl.
- You want the strongest suction and hands-free emptying → Shark, with its 80W motor and CleanTouch ejector.
- You are on a tight budget → compare both with our budget vacuum showdown too — there are even cheaper corded options if you don't mind the cable.

Frequently asked questions
Is the Shark UltraCyclone Pet Pro Plus good for cars?
Yes — it is explicitly designed for car messes and quick home cleanups. The motorized pet brush excels on car upholstery, and at 2.8 lb it is easy to maneuver inside a vehicle. Just note the ~10–15 minute runtime and 0.43 L bin: it is a touch-up tool, not a full-detail replacement.
Is the BLACK+DECKER Dustbuster still worth buying?
Absolutely. With 100,000+ Amazon ratings at 4.4 stars and the #1 spot in handheld vacuums, it remains one of the safest beginner buys. Its large dust bowl, rotating nozzle, and simple maintenance make it ideal for general car cleanup on a budget.
Which vacuum is better for dog hair in a car?
The Shark UltraCyclone Pet Pro Plus. Its detachable self-cleaning pet power brush is purpose-built to lift embedded pet hair from upholstery and carpet — the Dustbuster has no powered brush and needs more passes for the same job.
How long do these cordless vacuums run on a charge?
Both deliver roughly 10–15 minutes of real-world runtime per charge — enough for a full interior touch-up. The Dustbuster recharges in about 4 hours; the Shark takes 4–6 hours. Keep the vacuum docked between uses so it is always ready.
Can these replace a full-size vacuum for car detailing?
No. Handhelds are for maintenance cleanups — crumbs, dust, pet hair touch-ups. For deep cleans, especially wet messes, look at a dedicated wet/dry vacuum or a full detailing session.
